How was contact restored between NASA and Voyager 2? Here’s all you need to know about the ‘shout’ across interstellar space which retrieved the spacecraft

economictimes.indiatimes.com:

Voyager 2 spacecraft restored communication with mission control after a period of silence. The historic probe, launched in the 1970s to explore the depths of space, received an interstellar «shout» from the ground team across a staggering distance of over 12.3 billion miles. This signal prompted the spacecraft to turn its antenna back towards Earth, reestablishing the vital connection with mission control. After weeks of silence, this successful communication is a significant achievement for the Voyager 2 mission and allows for continued monitoring and data transmission from this iconic space exploration probe.

NASA's Voyager 2 spacecraft's restoration of contact was a remarkable feat of engineering and determination. After losing communication with the spacecraft last month, NASA's Jet Propulsion Laboratory (JPL) faced a challenging task to regain contact with the probe, which has been exploring space for an impressive 46 years.

The Deep Space Network (DSN), a network of giant radio antennas, detected a faint signal from Voyager 2 last week. Despite the signal not carrying enough strength to extract data, it served as a glimmer of hope for NASA. The spacecraft had inadvertently tilted its antenna just 2 degrees away from Earth on July 21, causing the communication breakdown.

In a daring and last-ditch effort, a Deep Space Network radio dish in Canberra, Australia sent out a carefully crafted message to Voyager 2, hoping it would reach the craft and command it to correct its antenna orientation. The odds were daunting, as the spacecraft was located billions of miles away in the
